Assurance
BP recognizes the importance of external and internal assurance from verifying a report to the independent monitoring of a project
We believe that independent assurance reassures readers and BP’s management that the information we publish is accurate, complete and material, and therefore contributes to building trust and credibility with key interest groups.
External assurance of sustainability reporting
We engage professional auditors who combine the strengths of financial auditing experience with technical competency in environmental and social standards.
As in previous years, we asked our group auditors Ernst & Young to provide assurance on our sustainability reporting based on the principles of the AccountAbility AA1000 Assurance Standard and the ISAE3000 International Federation of Accountants’ International Standard for Assurance Engagements Other Than Audits or Reviews of Historical Financial Information. This is the fourth year that our report has been assured against the revised AccountAbility AA1000 Assurance Standard 2008 principles of inclusivity, materiality and responsiveness.
Ernst & Young provide an independent third-party assurance statement in the report which can be found in this section as well as in the BP Sustainability Review 2012 pdf and printed document. The online pages included within the assurance process are identifiable by the Ernst & Young attestation footnote and link.
As part of the assurance process, Ernst & Young provide an annual report to the safety, ethics and environment assurance committee of the board, and present findings of the assurance process.
Our country-level sustainability reports are also assured by our group auditors.

Internal controls over non-financial management information
We have a formalized control system for the generation of non-financial management information (NFMI). For the processes that generate key recurring NFMI, we ask the BP employees who own these processes to annually assert the effectiveness of these controls, as a minimum. We support new or one-off metrics with proof points and take a risk-based approach to the validation of qualitative text. This process enables BP’s chief financial officer to assure the disclosure committee, made up of senior managers and including the group general counsel and auditor, on the accuracy and completeness of the various external reports prior to publication.
